Be it knovvn that I, ROBERT I-IoMoLLn, -a citizen of the Republic of .France, and resident of Paris, 2O Rue Guyot., F rance, have inventedcertain new and useful Improvements in Protective Casings for Safes,(for` Which I have filed an application in France,

on February 20, 1919, Patent No. 496,030

of Which the following is a specilication. K

This invention has for its object to provide a safe of any t-ype with a.protective casing, made of smoke producingmaterials, the construction ofthe casing being such that it can be applied not only to safes but alsoto strong-doors and even to the Walls of strongrooms of banks.

The accompanying drawing illustrates, by Way of example, how theprotective casing or shield is to be applied to a safe.

Since this smoke cannot be concealed it not only constitutes anexcellent means for attracting the attention of the attendants, but

also, because of its density and asphyxiating property, it tends toprevent the safe-blower from continuing his Work and compels him toleave the spot Where he was Working.

It is to be understood that the device may of course be composed of anyappropriate smoke producing materials, in particular when the lattercontain coal and hydrocarbon.

I cla-im as my invention A protective casing for safes, strong-doors andthe like, comprising an outer metal case,

and a Wall or layer of material for producing` a dense smoke arrangeddirectly aga-inst the inner surface of said case, so that when thelatter is penetrated by the flame of a blow pipe, such flame Willimmediately ignite said material, and the smoke generated thereby Willescape through the hole cut by the blow pipe and form a thick smokescreen which Will obscure the portion of thesafe on Which thesafe-blower is operating and thus prevent him from continuing` his Work,and

which Will also serve to Warn the attendants.`

In testimony whereof I have signed this specification.

ROBERT HOMOLLE.
